DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a button type container cap 100 according to the present invention includes a body 110 having a discharge hole 111 at an upper portion thereof, and a cover 120 provided in the body 110 to open and close the discharge hole 111 in a foldable fashion, and further includes a pressing part 140 integrally extending from the body 110 such that if the pressing part 140 is pressed toward a spaced part 130 formed in the body 110, the cover 120 is unlocked from the body 110, and a resilient button member 210 one side of which surrounds the pressing part 140 and the spaced part 130 and an opposite side of which is connected to the cover 120 to resiliently pull the cover 120 at the opposite side of the resilient button member 210 so that the cover 120 is rotatably open when the cover 120 is unlocked from the body 110.

Accordingly, the button type container cap 100 can be prevented from being damaged due to an external physical force, by the resilient button member 210 surrounding the pressing part 140 and the spaced part 130, and can be prevented from being deformed or damaged even if a pressing operation is repeatedly performed.

According to the embodiment of the present invention, as shown in FIG. 3, a sealing boss 121 is preferably formed on an inner bottom surface of the cover 120 at a location corresponding to the discharge hole 111 to seal the discharge hole 111 from the outside when the cover 120 covers an upper side of the body 110. As shown in FIG. 1, the sealing boss 121 protrudes from the inner bottom surface of the cover 120 toward the discharge hole 111 in an annular ring shape.

Meanwhile, as shown in FIG. 1, a catching step 141 is formed at an upper end of the pressing part 140, and an engaging step 123 engaged with the catching step 141 is formed at a portion of an inner surface of the cover 120 with which the catching step 141 makes contact when the cover 120 is closed.

The body 110 includes a cover connecting part 150 integrally connecting the cover 120 to the body 110 such that the cover 120 is rotatable with respect to the body 110.

As shown in FIGS. 1 and 2, the resilient button member 210 includes a body upper surface cover 220 surrounding at least a portion of an upper surface of the body 110, a spaced part cover 230 extending from one side of the body upper surface cover 220 to surround the spaced part 130, a pressing part cover 240 extending from the spaced part cover 230 to surround the pressing part 140, and a cover pulling part 250 extending from an opposite side of the body upper surface cover 220 and connected to the cover 120.

Accordingly, as shown in FIG. 2, since the resilient button member 210 including the cover pulling part 250, the pressing part cover 240, and the body upper surface cover 220 can be easily integrally formed with the cap body 110, the button type container cap 100 can be easily manufactured.

According to the embodiment of the present invention, the resilient button member 210 is preferably formed of a rubber or silicon material in the form of a plate.

Accordingly, the button type container cap 100 can be prevented from being damaged due to an external physical force, by the pressing part cover 240 of the resilient button member 210 surrounding the pressing part 140 and the spaced part 130, and can be prevented from being deformed or damaged even if a pressing operation is repeatedly performed.

As shown in FIGS. 1 to 3, the body upper surface cover 220 is formed lengthwise to cross the discharge hole 111 and surround the upper surface of the body 110 and a cover discharge hole 221 is formed at a location corresponding to the discharge hole 111, such that the sealing boss 121 of the cover 120 makes contact with and is attached to a circumferential area of the cover discharge hole 221 of a surface of the body upper surface cover 220 when the cover 120 is rotated and closed to cover the upper side of the body 110.

Accordingly, as shown in FIG. 3, since a portion of a surface of the body upper surface cover 220 formed of a resilient material such as a rubber which makes contact with and is attached to the sealing boss 121 of the cover 120 is pressed to be hollow, a sealing performance of the sealing boss 121 is further improved.

As shown in FIG. 1, the cover pulling part 250 has a plurality of bead protrusions 251 formed lengthwise on a plate surface of the cover pulling part 250.

Accordingly, since a pulling force (resiliently restoring force) of the cover pulling part 250 by which the cover 120 is pulled can be further reinforced by the bead protrusions 251, the cover 120 can be more promptly and flexibly rotatably open from the body 110 when the cover 120 is unlocked from the body 110.

Due to the configuration of the button type container cap 100 according to the present invention, the catching step 141 of the pressing part 140 and the engaging step 123 of the cover 120 are engaged with each other as shown in FIG. 3. Then, as shown in FIG. 4A, if a user presses the pressing part cover 240 of the resilient button member 210, the catching step 141 and the engaging step 123 are disengaged from each other as the pressing part 140 located on a rear surface of the pressing part cover 240 is moved toward an inner side of the body 110 through the spaced part 130. Then, as shown in FIG. 4B, as the cover pulling part 250 of the resilient button member 210 pulls the opposite side of the cover 120 with a resilient restoring force thereof, the cover 120 is promptly rotatably open.

Meanwhile, according to another embodiment of the present invention, as shown in FIG. 5, the body 110 includes a stopper 160 provided on an inner surface of the body 110 to face the catching step 141 with the spaced part being interposed therebetween, a stopper support boss 170 disposed at a rear side of the stopper 160, and an opening support part 180 extending upward from a location of an outer periphery of the body 110 corresponding to the cover pulling part 250 to further extend the cover pulling part 250 compulsorily when the cover 120 covers the upper side of the body 110.

Although the body 110 includes all of the stopper 160, the stopper support boss 170, and the opening support part 180 in the embodiment of the present invention, it is apparent that the body 110 may selectively include one or two of the stopper 160, the stopper support boss 170, and the opening support part 180.

Accordingly, if a user presses the pressing part cover 240 of the resilient button member 210 to rotate and open the cover part 120 so that contents in the container are discharged, the pressing part 140 of the body 110 is pressed toward the spaced part 130. Then, as an additional pressing movement is limited by the stopper 160, the pressing part 140 can be prevented from being plastically deformed or damaged by a repeated pressing operation. Further, as the stopper support boss 170 supports the stopper 160, the stopper can be prevented from being deformed or damaged. Further, as the cover pulling part 250 is further extended compulsorily by the opening support part 180, the cover 120 can be rotatably open from the body 110 more promptly and flexibly by the reinforced resilient restoring force when the cover 120 is unlocked from the body 110 due to a pressing operation of the resilient button member 210.

Accordingly, the button type container cap 100 can be prevented from being damaged due to an external physical force, by the pressing part cover 240 of the resilient button member 210 surrounding the pressing part 140 and the spaced part 130, and can be prevented from being deformed or damaged even if a pressing operation is repeatedly performed.

In addition, since the resilient button member 210 including the cover pulling part 250, the pressing part cover 240, and the body upper surface cover 220 can be easily integrally formed with the cap body 110 including the pressing part 140 and the spaced part 130, the button type container cap can be easily manufactured.
